06-02 22:21:50.615: e/androidruntime(869): java.lang.runtimeexception: unable start activity  componentinfo{com.inkadroid.mapa/com.inkadroid.mapa.mainactivity}:  android.view.inflateexception:     binary xml file line #2: error inflating class fragment 06-02 22:21:50.615: e/androidruntime(869):  @    android.app.activitythread.performlaunchactivity(activitythread.java:1647) 06-02 22:21:50.615: e/androidruntime(869):  @  android.app.activitythread.handlelaunchactivity(activitythread.java:1663) 

first need move <meta-data> tag under <application> tag in manifest.xml.

<meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" /> 

and minsdk="8" should change this

public class mainactivity extends activity 

to

public class mainactivity extends fragmentactivity 

and change this

<fragment xmlns:android="http://schemas.android.com/apk/res/android"       android:id="@+id/map"       android:layout_width="match_parent"       android:layout_height="match_parent"       class="com.google.android.gms.maps.mapfragment"/> 

to

<fragment xmlns:android="http://schemas.android.com/apk/res/android"       android:id="@+id/map"       android:layout_width="match_parent"       android:layout_height="match_parent"       class="com.google.android.gms.maps.supportmapfragment"/>
